Major X is actually Alexander Nathaniel Summers, the son of Cable and Storm from an alternate future; as is often the case with time-travelers associated with the X-Men, Major X’s future is quite bleak, as the mutants of Earth were largely wiped out by a being known as the Catalyst. The young Summers was raised in the X-Istance, a safe haven established by mutants and Atlanteans. There he was trained by his father to be the ultimate warrior, eventually joining the X-Command army and gaining the rank of Major.
Major X is quite the powerful mutant, as he has all of his father’s telepathic and telekinetic abilities, in addition to his mother’s weather manipulation.

The founder of the X-Istance was a mutant known as the X-Ential, who eventually went missing after disagreeing with the Atlanteans. This left the X-Istance in a vulnerable state, allowing the Catalyst to stage a deadly attack. With everything falling apart, Major X used his vehicle, the Motherbike, to travel back in time and find the X-Ential’s past self so he can restore the X-Istance in the future.As the son of Cableand Storm, Major X is quite the powerful mutant, as he has all of his father’s telepathic and telekinetic abilities, in addition to his mother’s weather manipulation.
